Upgrading your BizTalk application from an SQL send port to a WCF-SQL send port can be challenging, especially concerning schema compatibility.
Transitioning to WCF-SQL offers more functionalities such as better error handling and support for multiple message formats but requires careful schema management.
To upgrade, configure the new WCF-SQL port, set up the SOAP Action header correctly, ensure XML conformity, and test the port while watching out for common issues.
Ensure that XML aligns with the schema, verify parameter matches, handle namespace conflicts, and debug SOAP Action problems effectively to successfully complete the transition.
